Normal bristol or fire? Good or bad?

[gibec]

Are these harmful or harmless? They have a red tone so im wondering if these are fhe bad fire ones.

Whether its good or bad i dont want any ugly worms in my tank, but there is 1 more in the tank that i couldnt pull out so i need to know how urgent it is to gdt rid of them

Looks like a regular old bristleworm to me. Harmless.

Looks just like the ones I get in my sump. I just assumed they aren't fire type because I've never been stung picking them up.

Looks like a bristle to me (harmless) hope this helps:
